Succession and diel transcriptional response of the glycolate-utilizing component of the bacterial community during a spring phytoplankton bloom.

ABSTRACT: The influence of the phytoplankton-specific organic compound glycolate on bacterial community structure was examined during the 2004 spring phytoplankton bloom (February to April) in Dabob Bay in Washington. The diversity of the bacteria able to utilize glycolate during the phytoplankton bloom was determined using previously developed PCR primers to amplify the gene for the D subunit of glycolate oxidase (glcD). Many of the glcD sequences obtained represented novel sequences that appeared to be specific to marine environments. Overall, the glcD sequence diversity decreased as the phytoplankton bloom progressed. Phylotype-specific glcD quantitative PCR primers were designed for the six most commonly detected glcD phylotypes that represented distinct phylogenetic groups of heterotrophic bact
